T all whom t may concern:

Be it known t at oYD G. Dinnnr, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful lmprovements in Rotary gamators and Goncentrators, of which the following is a sp My invention relates to gamators and concentrat separation is effected in a rotating or barrel.

The object of my a simple and eiiicient so mounted various necessary adjustments `to adapt it for accurate regulation iii-conf the requirements and character rial to be operated upon To this end my novel rotary amalgamator and` which l reference Figure 1 chine.

Fig. 6 is a diagrammaticv viewv showing one c. linder or. barrel and the delivery trough withvits valve for dividing the tailings.l Fig. 7 is a diarammatic rview showing the body of concentrates in the cylinder or barrel. Fig. 8 is a longitudinal broken view, enlarged, partly in section and partly in elevatiorli, t e

12 is a feed hopper supported from the head end ofthe frame 2 and adapted to deliver into the head. end of the barrel. Being carried by the frame, the feed hopper maintains its position with relation rel under all conditions 'ustment vided with an inwardly leaving a feed yopening la of less diameter than the barrel but at the delivery end the barrel is open to its full diameter. The interior surface of thev barrel 3 is an amal# gamating surface. ke it, the barre` may l bedirectly plated, but I prefer to mak it a composite one,

The tailings pass oit from the barrel into the delivery trough l?, but as tl be e operated upon again, I have found it advantageous to use the switch valve 20 and the two branches 18 and 19. As will be seen by reference to Fig. 6, the heavier particles of the tailings tend to lag behind in the uprising movement. Now by setting the point of the valve 20 as shown, the heavier tailings may be directed and delivered separately from the lighter.
